Abstract: APPARATUS AND METHOD Abstract of the Disclosure An apparatus and method for producing a multiline output from a CO2 laser comprising an optical resonant cavity containing gaseous CO2, means for producing a controlled electrical glow discharge within the gas, such as Rogowski profile electrodes connected to a high voltage source, preferably mode locking means such as an acoustooptic modulator, and means within the cavity for producing a wavelength dependent loss, such as a Fabry-Perot etalon filter.  The apparatus and method disclosed in the specification greatly increase the efficiency of energy extraction from large CO2 laser amplifiers such as those contemplated for use in inducing nuclear fusion. The means for producing wavelength dependent loss within the laser oscillator cavity lowers the net gain of the usually dominant P(20) transition enough to allow the P(16), P(18), P(22), and P(24) transitions to successfully compete for available upper state population.  In prior art pulsed laser oscillators, only the P(20) transition reached laser threshold because of its anomalously high gain coefficient at the expense of the remainder of the nearby rotational transitions.  Thus in prior art lasers, the P(20) line dominated the output in all gain switched and mode locked Transverse Excited Atmospheric (TEA) laser oscillators, including electron beam controlled devices.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of assembling furniture corner joints between framing members, such as rails or boards set at angles to each other.  The corner joint is secured by connector plates, each of which has end positions set at right angles to each other correspond-ing with the angle of the framing members and having integral one-piece teeth struck from the body of the plate normal to the plane of the respective end position.  The teeth are of uniform length and are spaced apart in areas adjacent the end portions of the plate, leaving a smooth inner face on the connector plate in the area where the framing members would be brought together to form the joint.  The method is in two steps, one of which causes the teeth on one end of the plate to penetrate the face of the framing members and thereafter the opposite angular portion of the plate is moved relatively toward the second framing member to cause the teeth thereof to enter the framing member.  In each step the teeth, which are of uniform length, enter the adjacent face of the framing member in straight lines.  These steps enable a plurality of corner joints of one article of furniture to be assembled and secured in one operation by successive steps.

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for acoustical stressing of semiconductor wafers is disclosed, utilizing a number of small tungsten balls which are bounced on the surface of the wafer to be stressed. The movement of the tungsten balls is effectuated by clamping a wafer at one end of a con-duit, the other end being attached to a high intensity loudspeaker The loudspeaker is driven at resonant frequency of the clamped wafer and accordingly the tungsten balls bounce on the surface. This impact creates micro-cracks on the surface of the wafer and number and depth of these cracks can be controlled by power input and the number of tungsten balls utilized. Controlled stressing can thereby be accomplished both in terms of density of micro-cracks and location on the wafer.       Impact sound stressing finds utilization in the study of semi-conductor surfaces to determine effects of dislocations and micro-splite and in the evaluation of wafer polishing techniques. Structural changes in the original defect pattern due to oxidation can be studied ant a cause and effect relationship between damage and oxidation established.          The study of surface characteristics affecting many semi-conductor phenomena such as effective lifetime, noise, and contact potentials can be made in a controlled manner. Modern wafer polishing methods such as the cupric ton or silicon dioxide technique and others can be evaluated in terms of effectiveness of damage removal.        This invention is related to a United States Patent 4,018,626 entitled "Impact Sound Stressing for Semiconductor Devices by G.H. Sch?uttke and K.H.  Yang, assigned to International Business Machines Corporation and issued April 19, 1977.

Abstract: ABSTRACT OF THE DISCLOSURE        A rotatable airhammer includes an outer housing structure in which a hollow hammer piston is reciprocable to impact against an anvil bit used in drilling a bore hole.  The anvil bit has a central passage communicating with inner core sample tubing extend-ing through the piston to the upper end of the housing structure, such tubing housing structure being connectible to a string of concentric dual drill pipe extending to the top of the bore hole.          Compressed air is directed alternately to the annular space between the tubing and housing structure above and below the piston to reciprocate the latter for repeated impact action against the anvil bit, air being discharged from the lower portion of the housing structure to clear the bottom of the bore hole of cuttings and direct them into the central passage through the bit, the inner tubing and inner drill pipe portion to the top of the hole.          A gauge sleeve is mounted on the housing structure a short dist-ance above the lower end of the anvil bit, exhaust air from the air-hammer being directed into the bore hole immediately above and below the sleeve to provide a static air seal preventing cut-tings from passing upwardly around the sleeve, insuring passage of all cuttings into the central bit passage.  Exhaust air is also directed into the bore hole at a distance above the gauge sleeve to blow bore hole debris externally of the housing structure and drill pipe upwardly through the annulus around the drill pipe to the top of the bore  hole.

Abstract: ABSTRACT OF THE DISCLOSURE            A cage assembly for reinforcing concrete pipe.  In the production of concrete pipe, wire fabric cages are formed and concrete is cast around the cages.  The wire fabric con-ventionally comprises a plurality of crisscrossed strands, those strands running one way defining the longitudinal strands of the formed cage and those running the other way define the circum-ferential strands of the cage.  To reinforce the concrete pipe at the crown and invert regions thereof, stirrup members are welded to these portions of the cage.  The stirrup  members pro-ject radially outwardly from the cage and may be rigidly connected both to an inner cage and to an outer cage.  While the use of stirrups as presently employed ultimately renders the concrete pipe considerably stronger and more reliable, their use is both cumbersome and costly so far as assembly of the stirrups on the rolled cages.  The present invention provides a cage assembly which is more easily assembled and therefore less costly.  The cage assembly comprises a cage body having a plurality of longi-tudinal and circumferential strands, and a pair of mats, each formed of a network of interconnected strands.  One of the mats is located generally at the crown and the other located generally at the invert of the cage body.  Each of the mats includes a plurality of stirrup projections projecting from the surface thereof and projecting outwardly from the surface of the cage body.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention is directed to a wedge actuating drive for reciprocating cold reducing tube mills. The wedge drive is driven in common with the main crank which reciprocates the roll carriage, so as to be synchronized therewith. Upper and lower roll positioning wedges are arranged to be cyclicly inserted in and withdrawn from roll closing positions, by means of eccentric drive shaft means associated with each of the wedges, one above and one below the pass line for the workpieces.            Indexing drive means is provided for the eccentric shaft means, whereby during continuous rotation of the main drive shaft for the system, the eccentric drive shaft means for the wedges are actuated intermittently, so that wedge actuation occurs, as desired, only during the periods when the crank-driven roll carriage nears the end extremities of its recip-rocating stroke.           The use of an indexing drive means, rather than more conventional cam and toggle means, provides significantly greater long-term reliability in the operation of the roll positioning wedges, and enables significant reductions to be achieved in the construction cost of the equipment. At the same time, significantly higher operating speeds may be obtained.

Abstract: Abstract of the Disclosure An air conditioning system for a living space capable of operating as a heat pump or refrigerator employing a unitary compressor and expander having a common rotor with vanes defining enclosed compartments for positive compression of air in the compressor and positive expansion of air in the expander.  A regenerative heat exchanger having thermally coupled air passages is employed in the system together with a non-regenerative primary heat exchanger which is located in the warm space.  Air from the cool space is heated in the first passage of the regenerative heat exchanger, and moisture is injected, following which the air passes into the compressor inlet port.  From the compressor outlet port wet air flows at high temperature and pressure to the primary heat exchanger located in the warm space where some of its heat is given up.  Next the air flows through the second passage in the regenerative heat exchanger where its temperature is further lowered prior to being fed to the expander inlet port.  Air from the expander outlet port, at low temperature and at atmospheric pressure, is discharged into the cool space, the net result being to increase the temperature differential between the spaces.  When the system is used in the heat pump mode, the primary heat exchanger is located in the living space for heating the same, with the compressor-expander, initial air inlet, and final air outlet being located in the outside environment.  In the preferred form of the invention a separate primary heat exchanger is located in the outside environment and transfer valves are provided to substitute the outside heat exchanger and for switching the initial air inlet and final air outlet into the living space for use of the system in the refrigeration mode.  In an alternate form of the invention an auxiliary non-regenerative heat exchanger may be interposed between the final air outlet and initial air inlet.  When the system is employed in the heat pump mode, provision is made for use of a solar heat absorber between the regenerative heat exchanger and the inlet port of the compressor.
